4. 几个模版

(1) 弱引用handler

//handler
public static class MyHandler extends Handler {
    public final WeakReference<$className$> mWeakReference;

    public MyHandler($className$ activity) {
        mWeakReference = new WeakReference<>(activity);
    }

    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        $className$ activity = mWeakReference.get();
        if (msg.what == $code$) {
            if (activity != null) {

            }
        }
    }
}

(2)单例

//singleton
private volatile static $className$ sInstance;

public static $className$ getInstance() {
    if (sInstance == null) {
        synchronized ($className$.class) {
            if (sInstance == null) {
                sInstance = new $className$();
            }
        }
    }
    return sInstance;
}

private $className$() {

}

最后编写代码的时候输入快捷键就可以了
